Hi Mark
I am with Chris. Classic meets large scale performance and reliability
requirements.
I do not know any compelling reason to use BerkleyDB.
Interesting. I did some benchmarks a year ago on our production cluster
(see <http://markmail.org/message/xni5kqj2h3t6qjkd>) and saw a definite
difference between classic and BDB when both were run over NFS. Based on
those (and the fact that misbehaving users submitting several thousands of
jobs have crashed our scheduler not infrequently), I've been leaning
towards moving our install to BDB. Are there other tunables I should be
looking at?
